Hello!

To solve this equation, we need to isolate the variable on one side of the equation to see what it equals. 

As you can see, 2.7 is added. To get it onto the other side and cancel it from the one side, you will subtract it from both sides as shown below. Note that because of the commutative property, we can switch the places of 2.7 and x.

x+2.7-2.7=17-2.7  (Note that 2.7=2.7 is 0 in this equation.
x=14.3

Our solution is x=14.3

I hope this helped you learn how to solve equations a bit better!

For every 4 gallons of green paint he uses 3 gallons of blue paint. Drag the correct number of each type of paint into the box t
Inga [223]

Answer:

Amount of green color used =

\dfrac{64}{7}\text{ gallons}

Step-by-step explanation:

We are given the following in the question:

Every  4 gallons of green paint is mixed with 3 gallons of blue paint. to make a particular shade.

Ratio of green color to blue paint can be calculated as:

=\dfrac{\text{Amount of green color}}{\text{Amount of blue color}}\\\\=\dfrac{4}{3}

Amount of shade = 16

Amount of green paint = 4x

Amount of blue paint = 3x

Thus, we can write:

4x + 3x = 16\\7x = 16\\\\x = \dfrac{16}{7}

Amount of green color used =

4x = 4\times  \dfrac{16}{7} = \dfrac{64}{7}\text{ gallons}

Amount of blue paint used =

3x = 3\times  \dfrac{16}{7} = \dfrac{48}{7}\text{ gallons}
